Meester, hij begint weer!

Just while André Buys gives sex education classes and his mother away on pilgrimage, baby boy Jan is left at his doorstep with a note implying he's the father, no clue to the mother. Buys brings it temporarily to school, where the cleaner resigned, so a former one is called back. She had affairs with both Buys and his former pupil Jean-Pierre, handsome rowdy motor-biker son of the haughty principal, who 'visits' her for cash. Meanwhile Millar was tricked into temporarily running the pub and a nerd seeks love - rather then sex advice.
